To all whom it may concern:

Be it known that I, SAMUEL \V. RAYMOND, a citizen of the United States, and a resident of Adrian, in the county of Lenawce and State of Michigan, have made an invent-ion appertaining to a Tractor Cultivator; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to the characters ot reference HitlTiICCl thereon, which form a part of this specification.

My invention has for its object to provide a cultivator structure that may he readily attached to tractors. It partimilarly has for its object to provide means .tor controlling the depth at which the cultivator plou s will I operate on the soil, and means for inanipu lating the cultivator structure or parts thereof to remove the cultivator plows from. the ground Moreover, means is provided forreadily adjusting the position of the parts of the cultivator structure to the distance bet-Ween the rows of vegetation to he cultivated. The invention has for its object other advantages and features which 'will appear in the following, description and drawings.

The invention may be contained in structurns Wl'iich vary in their details. To illustratc practicalepplication of the invention I have selected a structure containing the invention and shall. dcscrihc the structure thus selected hereinafter. 'lhe particular structure selected is illustrated in the accompanying drawing Figure 1 illustrates a side view of the cultivator. 2 illustrates a top view. l5 3 illustrates a front view of the cultivator. Figs. 4 and 5 illustrate the dctai s of a hall and soclzct joint connecting parts of the structure. Fig. 6 illustrates a partly broken view of the tractor and a cential cultivator 'ti'alnc. Fig. 7 is a sectional view taken on the line 7---'? indicated in Fig. 5'. Fig. 9. is a sectional view taken on-the line SS -8 indicatcd'in Fig.

in the drawings, 1 is the frame of the tractor. The frame i provided with an arm 52 in which is supported a castor wheel 3. The caster wheel is operated by the hevcllcd gear Wllfifilfii and the bevelled gear wheel 5 being connected to the steering 1922. Serial No. 591,686.

wheel 6 which is suitably located with refer-- ence to the drivers seat 7. The hull Wheels 3 of the tractor are supported on stub axles that are secured in castings E) in which suitable extensions 10 for the jack shaft of the tractor are also supported. The jack shaft is divided and is independentiy and diliferentially driven in the manner well known in the art. Thus the tractor may he steered by clutching one of the parts of the jack shaft and allowing the engine to drive the tractor through the other part of the jack shaft, which will cause one of the bull Wheels to be held stationary While the other is rotated. the vertical axis in the bull wheel, that is held by the clutch, \vhichextends throng). the hub of the wheel. The guiding means, being a caster wheel will follow the swing of the leading end of the tractor. particularly convenient in the turning at the ends of the rows oi vegetation, and by proper manipulation as between the clutch ing means and. the steering wheel, destruc tion of vegetation during; the turning, operations is easily avoided.

The cultivator structure is particularly adapted and may be used with great advantags in such a tractor. The cultivator is formed of three parts which enables the complete cultivation of two rows of vegetation at the same time. The parts between the rows are cultivated by the plows 11 that are secured to the frame 12. The frame 12 is connected by means of the cross rod 13 to the uprights 14 Which are secured to the frame 1 of the tractor by suitable bolts. Their depth is regulated by the seuti'er or drag 15. The scatter ordrag may he formed of a steel. plate having a serrated edge 16 which extends across the major portion of the distance between the rows. The scutier 16 being located behind the plows 11. operates to break up and pulverize the soil, par ticularly on the surface thereof, after it has been cultivated by the cultivator plows. 'lhe scuiier i5 is located at an angle, it heinu inclined upwards and towards the forward end of the tractor. It thus not' only o ierates to break up the soil, but also to regulate the position of the frame 12 with reference to the surface oil the soil. The forward end of the frame 12 is located in proximity to the castor Wheel. 3 and the scuifer is located in proximity to the line This will swing the tractor around This is 7 till III

connecting the. points of contact oi the hull. wheels-with the soil so that notwithstanding the grade changes of the soil over which the tractor passes, the depth of the cultivator plows will be maintained uniform, with the result that the ground will be uniforml v cultivated, that-is, cultivated to a uniform depth, by the cultivator plow 1].

The outer sides of each pair of rows of vegetation are cultivated bv the cultivator plows 17 which are connected to the frames 18. The frames 18 are pivoted to the frames 19 and are supported by the said frames 19 and the push bars 20 -to which the frames 18 are connected by the rods 2i.

The frames 19 are supported by the castor wheels 22 pivotally mounted on the vertical bars 23. Each bar 23 extends through a l'iifurcated part of the frame 19 which forms bearings, for the shank, or vertical bar 23, of the Castor Wheel 22. The relative posi- "tion of the frame 19 to the bacilli may be adjustal'ily located by a pin 2t that may be inserted in any one of the holes 25 formed an the upper end of the bar The position of the bifurcated end of each frame 19 relative to the central longitudinal line or axis of the tractor frame is deter mined by the jointed irame or toggle 26 having the two parts 2't' land28. The part 27 is also provided. with "a bifurcated end that is located within the bifurcated end of the frame 19 through which the shank or vertical bar 23 of the caster Wheel 22 also extends. The parts 27 and 28 have bifurcated ends that intertit. They are connected togather by the pin or bolt 25). The remaining end of the part 28 is connected for universal movements by the ball and socket joint 30, the ball 31 being secured to the end of the part 28 and the socket- 32 being secured to the bar 14. The socket 32 may be "formed of two parts 33, one of which is secured to the bar l"- and the other pivotally connected therewith, suitable clamping bolts 3 being provided for securing the parts 33 together and enclosing the ball 31.. joint of the toggle is located a yoke 35 which substantially [its the bifurcated. end of the part 25%. The yoke 35 is pivotally connected to the parts 27 and 28 by the pin .29. rod fltl connected to the yoke 35 and to a lever 87. The lever 25? is secured in position at any desired point along a backing sector 38 of the type well known in the art. il'l ovemcnt of the lever 37 operates to swing the part 28 forward or back, and the push rod 20 beingconnected to the tractor frame, securest-lnough the frame 15), the outer bifurcated end of the part 2- from forward or backward movement, With the result that movement of the lever 37 causes a lateral movement of the frame 19, with the consequentlateral movement of the Thus the dis- 'formed by the pin 29. p is moved in one direction the entire side At the tance of each frame lfrom the (enter line of the tractor may be readily adjusted by the operation of the lever 37.

If it is desired to prevent the plows from engaging the ground during movement of the tractor, either or both of the l'rauus l8 may be raised by the lever Ill) that lliovcs over a locking sector 40. The lever 23.) is (011' nected by cables 41 that pass through th pulleys 4:2 to the toggles 2G, and from the lever 39in one case and the :Ulll 48 in the other case. The arm 48 is connected to the lever 39 by the shaft 49. It may be con-- nected to the part 27 near the toggle joint i l hen. the lever ll."

harnesses, to which the cultivator plows l? are connected, are lifted. The side harnesses may thus be lifted well above the vegetation. This is of particular advantage inv turning at the end as the pairs of rows are completed. The of rotation of each side harness extends through the ball and socket joint 36 and the ball 4-3 that is connected to the end of the push rod 20. Each ball 43 is located between a pair of pins or bolts 44: and a pair of flanges 45 formed on the frame 1. ol: the tractor. T his forms a universal connection between the end of the push rod 20 and the tractor frame to permit, not only lateral movements of the other end of the push rod 20, but also the swinging movement that is induced by the operations of the lever 39. The sector fid and the lever 37, moreover, are connected to the end of the push rod 20 near the ball 13. Therefore the toggle is not materially ail'eeted when the side harness is raised.

The frames 19 and 26 form an arched jointed'arm that extends to the leading end of each of the framesl8, and thus the cultivator may be used for cultivating corn after it has reached a considerable height in its growth.

If desired. the central harness may also be raised by a suitable lever and a link or cable connection. lo the form of the constriuttioi'i shown, the lever 39 and the arm 48 are connected by links 50 and spring 56 to the bell crank lovers 5]. that are pivotally mounted on the tralne l. The bell crank lover's are connected to the central. Frame 12 by means of the links 52 that are connected to the trout and back corners of the trance 12 whereby the frame 12 lifted from the ground sutticiently to cause the cultivator plows It to clear the ground upon the operation of the lever 39. The frame 12 being connected to the cross bar 13 by means of the links 5333 enables this lifting operation through the links The plows are adjusted lattn ally by the pins 5-1 and the holes Also the greatest, depth of the plows are adjusted by the pins 57 and the holes 58.
